With the development of the society, the improvement of people's living standard namely the heat type home appliance is popular in the market in recent years with the prominent advantage of saving time, water and electricity. And namely the heating element of heat type home appliance also follows the law of survival of the fittest, performance and quality are good by the choice, bad be eliminated. According to the in-depth understanding of the heating chip on the top ten instant home appliances on the market, domestic ceramic heating elements have been basically eliminated by 2015, while quartz tube and red copper heating elements instant electric water heaters are on the decrease. At present, the instant heating elements widely used are cast aluminum heating elements and stainless steel thick film heaters. The main differences between the two heaters are as follows:
Cast aluminum heater: large volume, easy product thermal inertia, slow thermal response, low thermal conversion rate, easy scaling. But resistant to dry burning, pressure, changeful shape, relatively low price. However, the new favorite of the hot heating tube, Jada Andone series stainless steel thick film heating tube has more powerful application advantages: high power density, compact size, bearing and durable without power attenuation, fast thermal response, not easy to scale, and the heat conversion rate is as high as 96% above.
Hot water can be produced after the thick film heating tube is electrified for about three seconds. The water temperature can reach 98-99 degrees, and the surface working temperature of the heating tube can work normally within 400 degrees. At present, the power of instant hot water using Daditong series stainless steel thick film heating tube is mainly 4000W and 5500W.
Thick film heating technology originated in Europe and the United States, it is the use of screen printing, insulating medium, resistance, conductor? Materials such as protective glaze are printed on the substrate and sintered at high temperature.
Film heating element has the advantages of fast response, high thermal efficiency, high power density, safety and durability. In particular? Is the fluid (water, oil) heating, is more stable, obvious advantages.
